First replace the letters with the numbers it gave so you have 3(2)(7)^2-(2)^2
multiply the 3 and 2 together to make 6(7)^2-(2)^2
do seven to the second power (7x7) so you get 6(49)-(2)^2
-(2)^2 is the same as -1(2)^2, so that can just become -2^2. so you now have 6(49)-2^2
multiply 6x49 so you have 294-2^2
do two to the second power (2x2) so you get 294-4
294-4=290
Answer:
133/1152
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
19+15+14 = 48 marbles
Of which 19 are red, 15 are yellow and 14 are blue.
What is the probability of pulling out a blue marble, followed by a red marble, if you replace the blue marble first
Blue marble
48 marbles, of which 14 are blue.
So 
Red marble
48 marbles, of which 19 are red.
So 
Both:

So the correct answer is:
133/1152

Answer:
24
Step-by-step explanation:
The angles of a linear pair are supplementary.
(6x +3)° +33° = 180°
6x = 144 . . . . . . . . . . . divide by °, subtract 36
x = 24 . . . . . . . . divide by 6
Answer:
This is not correct
Step-by-step explanation:
He could have rolled a 6 on the second roll without rolling a 6 on the first roll, the first roll had ZERO effect on the second one to be able to change what he would roll
